Breaking through ice is read as a sudden loss of footing on ground that looked solid. Dream books link it to risk taken too lightly or feelings frozen over that give way.
Has this come up in your dreams before? What was going on in your life then?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
